T 0 all whom it may concern: 1 Be it known that I, EILERT WEERTS, citizen of the United States, residing at Wentworth; in the. -county of Lakeand Stateof South Dakota, have invented certain new' and useful Improvements in Agricultural the meansfor effecting the result, reference is to'be had to the following description and accompanying drawings. 1

While the invention may be adapted-to difi erent forms and conditions by changes in the structure'and' minor details without de partin from the spirit or essential features thereo still .the preferred embodiment is shown in the accompanying drawings, in

which: p

S is a detail View of a cultivator attachment ofthe disk type."

Fig. -9 is a detail perspective view of the means for throwing the rotary pulverizer into and out of gear.

Corresponding and like parts'are referred to in the following description and indicated in all the views of the. drawings by the same refcrencecharacters. I

The $03.11! frame 11s mounted upon an axle 2 so-as to turn thereon and admit of the devicesfitted to the rear portion being raised or' lowered. Ground wheels 3 are fitted to the end portions of the axle 2 and are adapted to be connected therewith bya ratchet meche anism'to admit of one round wheel turning faster than the otherwit rout binding,as when 1 Fig. 2is a side making a curve. The pole or tongue 4 is connected with the axle 2 in-a manner not to interfere with p the rotation of said axle. Braces 5 are connected at their front ends with the .ole '4 and are mounted upon the I axle 2 at t eir rearends. Suitaple means are provided between the front end of the frame 1 and the pole or tongue 4 for raising and lowering said frame to adjust the rotary pulverizer or other attachment fitted to therear end of the frame to the required elevation.

As shown most clearly in Figs. 2 and 6, a hanger 6 is pendent from the rear portion of the pole 4, and a forked lever 7 is ivo'ted to the lower end thereof, the fork mem ers curving'u'pwar'dly and embracingopposite sides of the pole and having' spring connection with the front end of the frame 1. 4 An operating lever 8 is connected with the rear .end of the forked lever 7 and extends upwardly along one side of thepole 4 within convenient reach of the drivers seat 9. A toothedbar 10 cooperates'with the leverS to secure-it and theframe 1' in the required adjusted position.

shaft 11 is mounted .'in' bearings provided at the rear end of the frame, said bearings being of such construction as to admit of the shaft 11 having a limited vertical movement so as to prevent injury to the operating parts when coming in contact with a stone,' root or-otherlike obstruction. A

sprocket wheel 12 is loosempon each end of t e shaft 11. and a s rocket chain 13 con-- nects it, with a sproc 'et wheel 13 either fast to theaxle 2 or to.the respective ground wheels 3. A disk or head 15 is mounted I upon each end portion of the shaft-11 so as to rotate therewith and supports a series'ol' rods '16 which are mounted therein.

2 and 5,-or may. be provided with cultivator disks. 17, as indicated in Fig. 8 said disks being slipped upon the rods and held apart -by means of spaced slips 18. Asshown most clearly in Fig. 5, teeth 19 and 20 pro- The. rods 16 may be toothed, as shown in Figs. 1,-

ject from opposite sides ofthe rods 16, t ierc' being about twice as many teeth 20 as 19, so-

that the rods may be set. either for fine or -coarse work.

and cooperate with spring actuated pawls 22,

tion about at a right an le to'the surface of the ground or incline eit ier forward or rearward according to the nature of the work,.

7 Notched or toothcddisks 21. are fitted to projecting ends of the rods 16 which latter hold the rods 16 in an adjusted position so that the teeth may occupy a posicondition of soil or result to be effected. Upon turning the rods 16 to cause the teeth 19 and 20 to occupy an approximately tangential arrangement, the-'rotar pulverizer presents a surface consisting of longitudinal rods and short projections, or in other words, the device presents the appearance of a drum or cylinder having an. open work surface to crush clods and level and pulverize the soil. One or both of the heads 15 may be easily removed, whereby provision is had for interchanging the rods 16 so as to provide either a toothed surface or a surface embodying disks 17, as will be readily understood.

When it is required to cut weeds, grass or the like, the rotary pulvizer may be replaced by the cutting mechanism illustrated 111 Fig. 7, the same consisting of a cutter head 23 mounted upon the shaft 11 and a cutter bar 24, the latter being attached to the main frame in any manner so as to cooperate with the cutter head 23 after the manner of the well known lawn mower.

The shaft 11, heads 15 and rods 16, with their teeth 19 and 1.0, or the disks 17, con stitute the rotary pulverizer or clod crusher,

and in some instances it may be dcsirahle to throw the same out of gear and for this purpose levers 25 are provided and are arranged to move the sprocket wheels 12 upon the shaft 1] so as to unship the clutch 2c. The levers 25 are adapted to be actuated from the drivers seat by means of a lever 27.

Having thus described the invention, what is claimed as new is:

In combination a rotary support, rods provided with rows of differently spaced teeth, toothed disksfitted to the ends of said and cooperating with the toothed disks to hold the rods in an adjusted position with rows of teeth spaced in one way out of service when differently spaced rows are put into service.
